  30 .Sh NAME
  31 .Nm killall
  32 .Nd kill processes by name
  33 .Sh SYNOPSIS
  34 .Nm
  35 .Op Fl delmsvz
  36 .Op Fl help
  37 .Op Fl u Ar user
  38 .Op Fl t Ar tty
  39 .Op Fl c Ar procname
  40 .Op Fl SIGNAL
  41 .Op Ar procname ...
  42 .Sh DESCRIPTION
  43 The
  44 .Nm
  45 utility kills processes selected by name, as opposed to the selection by pid
  46 as done by
  47 .Xr kill 1 .
  48 By default, it will send a
  49 .Dv TERM
  50 signal to all processes with a real UID identical to the
  51 caller of
  52 .Nm
  53 that match the name
  54 .Ar procname .
  55 The super-user is allowed to kill any process.
  56 .Pp
  57 The options are as follows:
  58 .Bl -tag -width 10n -offset indent
  59 .It Fl d | v
  60 Be more verbose about what will be done.
  61 For a single
  62 .Fl d
  63 option, a list of the processes that will be sent the signal will be
  64 printed, or a message indicating that no matching processes have been
  65 found.
  66 .It Fl e
  67 Use the effective user ID instead of the (default) real user ID for matching
  68 processes specified with the
  69 .Fl u
  70 option.
  71 .It Fl help
  72 Give a help on the command usage and exit.
  73 .It Fl l
  74 List the names of the available signals and exit, like in
  75 .Xr kill 1 .
  76 .It Fl m
  77 Match the argument
  78 .Ar procname
  79 as a (case sensitive) regular expression against the names
  80 of processes found.
  81 CAUTION!
  82 This is dangerous, a single dot will match any process
  83 running under the real UID of the caller.
  84 .It Fl s
  85 Show only what would be done, but do not send any signal.
  86 .It Fl SIGNAL
  87 Send a different signal instead of the default
  88 .Dv TERM .
  89 The signal may be specified either as a name
  90 (with or without a leading
  91 .Dv SIG ) ,
  92 or numerically.
  93 .It Fl u Ar user
  94 Limit potentially matching processes to those belonging to
  95 the specified
  96 .Ar user .
  97 .It Fl t Ar tty
  98 Limit potentially matching processes to those running on
  99 the specified
 100 .Ar tty .
 101 .It Fl c Ar procname
 102 When used with the
 103 .Fl u
 104 or
 105 .Fl t
 106 flags, limit potentially matching processes to those matching
 107 the specified
 108 .Ar procname .
 109 .It Fl z
 110 Do not skip zombies.
 111 This should not have any effect except to print a few error messages
 112 if there are zombie processes that match the specified pattern.
 113 .El
 114 .Sh ALL PROCESSES
 115 Sending a signal to all processes with uid
 116 .Em XYZ
 117 is already supported by
 118 .Xr kill 1 .
 119 So use
 120 .Xr kill 1
 121 for this job (e.g.\& $ kill -TERM -1 or
 122 as root $ echo kill -TERM -1 | su -m <user>)
 123 .Sh EXIT STATUS
 124 The
 125 .Nm
 126 command will respond with a short usage message and exit with a status
 127 of 2 in case of a command error.
 128 A status of 1 will be returned if
 129 either no matching process has been found or not all processes have
 130 been signalled successfully.
 131 Otherwise, a status of 0 will be
 132 returned.
 133 .Sh DIAGNOSTICS
 134 Diagnostic messages will only be printed if requested by
 135 .Fl d
 136 options.
 137 .Sh SEE ALSO
 138 .Xr kill 1 ,
 139 .Xr sysctl 3
 140 .Sh HISTORY
 141 The
 142 .Nm
 143 command appeared in
 144 .Fx 2.1 .
 145 It has been modeled after the
 146 .Nm
 147 command as available on other platforms.

 151 .Nm
 152 program was originally written in Perl and was contributed by

 154 this manual page has been written by
 155 .An J\(:org Wunsch .
 156 The current version of
 157 .Nm
 158 was rewritten in C by

 160 using
 161 .Xr sysctl 3 .
